The update process of unc0ver is not complicated. The first step is to restart the iPhone or iPad device to lose the jailbreak. Then, once the team is operational again, you must install the latest version of the tool through Cydia Impactor. Follow our tutorial on how to install and run the unc0ver jailbreak.
The unc0ver jailbreak is compatible with all iOS devices that have the operating system version iOS 11.0 to 11.4 beta 3. The iPhone and iPad with iOS 12 can not benefit from it, and currently there is no tool available for them. If your device has iOS 10, there are other methods with which you can use to jailbreak.
